Specification of Letters Patent.

Application filed August 22, 1918.

Patented Mar. 10, 1914. Serial No. 786,091.

To all whom it may concern:

-Be it known that I, HERBERT H. STEELE, a citizen of the United States, and resident of Marcellus, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type \Vriting Machines, of which the following is a specification.

My invention relates to key operated devices for typewriting machines and its general object is to provide new and improved ke operated devices for controlling movablh parts and particularly the stop setting and stop retracting devices of key set tabulating mechanism, especially when such mechanism is of the magazine style.

Another object of the invention is to provide novel full-stroke devices for key set tabulating mechanism.

Another object is to provide a simplified and improved construction of stop magazine or container.

Another object is to improve the construction and mode of operation of key set tabulating mechanisms of the magazine style.

To the above and other ends which will l1ereinafter.appear, my invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

In carrying out my invention in the pres ent instance Lhave, as shown, applied it to a No. 3 Monarch typewriting machine and to key set tabulating mechanism of the charactor disclosed in my prior Patent N0. 1,637,076 of August 27, 1912, although it is to be understood that the principles of the invention may readily be embodied in other styles of writing machines and of tabulating mechanism.

In the accompanying drawings, Figure 1 is a fragmentary side elevation, partly in section, of a Monarch t-ypewriting machine embodying my invention, parts of the machine being omitted and parts broken away. Fig. 2 is a fragmentary side elevation of certain of the escapement devices and sto ejecting devices shown in Fig. 1. Fig. 3 IS a vertical sectional view taken on a plane indicated by the broken dotted line 10 m in Fig. 1. Figs. 4, 5 and 6 are enlarged views illustrating the details and operation of the novel key mechanism, Fig. 4 being a vertical section taken through the key stems, Fig. 5 partly in vertical section and Fig. 6 in side elevation. F i 6 is a iragmentary front view of the eft-hand front corner post and associate parts. Fig. 7 is a top plan view showing an improved con b0 struction of stop me azine or holder comprising two parts. ig. 8 is a transverae sectional view taken on a plane indicated by. the dotted line 3 in Fig. 7 and looking in the direction of the arrow at said line. 66 Figs. 9 and 10 are respectively side and end elevations of the main part of the sto magazine holder shown in Fig. 7. Figs. 1 and 12 arcorresponding views of the other part of the stop magazine.

As shown in Figs. 1 and 2, the main frame comprises a base 1, posts 2 and a top plate 3 supporting goose-neck standards 4 to which are fixed grooved track-ways 5 and 5- cooperating through anti-friction balls 7 76 with the grooved rear bar 8 of a platen carrier or carriage which further includes forwardly extending end bars 9. The end bars 9 provide bearings for a rotary platen 10 with the, front face whereof coiiperate type bars (not shown) which are supported on a shifting segment and are operated by trains of devices each comprising a sub-lever 11 pivotally connected with a key lever 12, the set of key levers being arranged within the 8Q base of the machine. The carriage is constantly urged leftward by a motor or spring drum (not shown). Pivoted to the end bars 9 are arms 13 which support a springprcssed feed rack 13 that meshes with a pin 00 ion 14 operatively connected to a toothed escapement wheel 15. Cooperative with the escapcment wheel are dogs 16 mounted on a dog rocker 17 which is pivotally supported on a bracket 18. A link 19 connects the dog rocker with a pivoted universal bar frame 20 carrying a universal bar proper 20 which underlies the key levers 12.

The denominational tabulating mechanism of the machine comprises a set of up- -right denominational stop levers pivoted at 22 in a frame 23 secured to the main: frame. The upper end portions of the levers '21 are curved forward terminating in denominational stops proper 24, said stops being arranged a letter space distance apart lengthwise of the carriage and bein ada ted when actuated or projected horizonta 1y forward to cooperate with column sto s hereinafter described. The actuating 110 ducing the cost of manufacture.

vices for the stop levers 21 comprise slide bars 25 which bear at their rear end portions on a part of the frame 23 and are adapted to push against the lower arms of the levers 21. The forward ends of the bars 25 bear slidably in a detachable supporting frame 2e and are adapted to be actuated by arms 27 secured to short rock shafts 28 bearing in upright portions of the frame 26. Fixed to the rock shafts 28 are levers '29 provided with denominational tabulator keys 30. When a key 30 is actuated it rocks the associate shaft 28, causing the crank arm 27 to slide the bar 25 rearward, the latter swinging the associate lever 21 on its pivot and projecting the stop 24 into the path of the column stops.

The actuation of one of the stop levers 21 operates carriage releasing devices comprising a universal hail 31 having end portions 32 pivoted at 33 to the frame One of the end portions has an extension 32* which is connected by a link 34 to one arm of a lever 35 pivoted at 36 to a stationary bracket .37, said lever arm being connected at its end with a lifter 38 which has shoe portions un derlying the feed rack 13. \Vhen the universal bail 31 is swung rearward by. one of the stop levers 21 said bail OPQIEIiQBS'thIOUgh the train of connecting devices to raise the lifter 38, separating the feed rack from the pinion 14 and permitting the carriage to be drawn rapidly leftward by the carriage motor. The usual restoring springs are provided for the carriage releasing and denominational stop mechanisms.

Projecting rearward from the slide bar 8 are arms 39 which provide a support for a column stop bar 40 that is toothed at its front and rear faces to form notches for receiving column stops 41 that are retained in place on the stop bar by aspring pressed locking rod 40 housed within a groove in the front face of the stop bar.

The stops 41 when not in use are adapted to be housed within a stop magazine or holder of novel construction comprising essentially as is clear from Figs. 7 to 12, two U-shaped parts 42 and 43, the part 42 being shown detached in Figs. 9 and 10 and the part 43 being similarly shown in Figs. 11 and 12. The two parts 42 and 43 are made of cast metal of suitable composition and all machine work is eliminated, thus greatly re- 7 The part 42 which may be said to be the main part comprises a Ushaped body portion 44 and a head 43 as well as a barrel or cylindrical portion 46 at the opposite end from the head. The part 43 is U-shapcd in cross section and forms the downward sides and floor or bottom of the magazine proper. The two parts after being cast are ready for assembling without requiring any finishing or other ad 65 ditional work; and when assembled or interseated as illustrated in Figs. 7 and 8 are detachably secured together by screws 47, said screws passing loosely through holes in the edge portions of the part 42 and be- 'ing received in tapped holes formed in lugs 48 on the part 43. The two-part magazine after being assembled may be adjustably attached to the machine frame by screws 49 passing through slots 50 formed in lateral ears 42 on the part 42, said screws enga ing in tapped openings in the carriage. rail 5. The part 42 has vertical guide ways 51 and 5; east in its head 45. These guide ways receive respectively the slidable stop ejector and stop retractor hereinafter described and have been. found in practice to provide for a smooth and effective control and guidance of these slidable parts or pieces. Further the barrel portion 46 is open at its righthand end and is slightly flared to receive and fixedly hold by a driving fit or otherwise a tapered plug or end piece 53 which is rigidly connected to a supporting rod 54, said rod and said plug being preferably made of steel.

The column steps 41 are arranged or stored on the support or rod 54 as in my prior patent aforesaid, being pressed outward along the rod 54 by a sprin pressed follower (not shown), and are a apted to be forced downward off the rod and projectcd through a slot-way or opening 55 formed between the edge of the floor portion 56 of the part 43 and the inner face of the head 45. The magazine is arranged directly above the column stop bar and the slot-way 55 is above the top of the bar so that when the column stops are ejected through the slot they will be forced downward to engage with the notches of the stop bar. The ejecting or stop controlling devices comprise, as disclosed in my prior patent aforesaid, a device, element or slide 57 which is arranged iii and guided by the groove 51 in the head 45. A retractor element or slide 58 fits into the parallel guiding groove 52 and is adapted to retract the steps 41 from the stop bar 42 into the magazine, said retractor being arranged at the forward side of the stop bar and when in normal position extending below the stop bar and terminating at its lower end in a lug or toe piece 59 which underlies the forward portions of the set column stops. The (.JGCtUl 57 is operated by a train of key eontrollcd devices comprising an upright angular link 60 connected through a shouldered screw 61, with the ejector 57, the lower end of said link being pivotally connected with a crank arm 62 extending rearward from a rock shaft 63, said crank arm being provided with a hub 64 which fits 0v r the inner end of the rock shaft and is pinned thereto. The

'roek shaft bears at its right-hand end in the forwardly turned ears 65 of a bracket 66 aforesaidcbut the rod 70 instead of being providedwith a rigid key at its front end as in, said prior construction'is associated with novel devices to be presently described. The

- retractor 58 is operative by a similar train ofrstop controlling devices, said retractor being provided with a lateral shouldered screw 1 which pivotally supports'the up- .'per end of a link 7 2,-the lower end of said ink being pivotally. connected to a crank farm73 extending rearward from a sleeve 74 to the ri ht-handend of which said crank arm. is xed. The sleeve surrounds and bears loosely on the rock shaft 63, being confined between the crank arms 73 and 69. Fixed to the left-hand end of the sleeve 74 is a downwardlyextending crank arm 75 to which is connected a forwardly extending rod or like 76.

The rods, elements or devices and 76 bear near their forward ends'in cars 77 'loent n that the column stops during the stop ejectin and stop retracting operations were lia lale because of faulty or insufiicient opera,- tion of the actuating keys to be arrested in the magazine entrance way when partly on and partly off the column stop bar, the stop bar and the magazine constituting relatively movable elements or stop supportlng devices,

on one of which, inthe present instance the magazine, the column stops are normally mounted and from which said column stb s are adapted to be moved to and upon t e other of said elements, in this case the column stop bar. The operator not being aware of this defective operation would thereafter attempt to move the carriage to the right or left and the result would sometimes be that the carriage would become jammed fast by the partially ejected or retracted stop, causing considerable trouble and annoyance before it could be freed. Various means for obviating this defect have been devised heretofore including full-stroke devices but the plans heretofore suggested have all been open to objection of some sort, some of the position shown inractice heretofore it has been found suggested devices being complicated in construction and others being found not easy of application. For example, it has been found difficult to adjust and adapt full-. stroke devices of the usual character because of the short motion which is imparted to the stop set and stop retracting keys. My present invention is designed to overcome the defects and objections above noted and others in connection with key operated mechanism, and to this end I provide novel power storing and trip mechanism, associating with each key in the present instance a power device compression spring in which is stored up by the key action eflicient power to operate the devices associated with said key. To insure a full movement of such devices the operator must depress the key the full distance, as otherwise the ke returns without accomplishing anything,- ue to the fact that the trip which releases the compression or power spring is only operated at or near the end of the key action. The result is that a column stop cannot be ejected or withdrawn only part of the distance, the o erator being unable to shift the stop except t rough releasing the compression spring and as soon as, this occurs the devices are withdrawn from the control of the operator, the spring performing the operation of setting or retracting the stop. Of course, it is only necessary to store sufficient power in the spring to insure that the stop setting or retracting movement under its control shall be full and complete. It will be understood that the intermittently acting power springs are opposed by the constantly acting draw springs 80 and 81 and to be effective must overcome said opposing draw sprin 3.

Referring more in detail tothe preferred embodiment of my invention and which is clearly illustrated in Figs. 1 and 4 to 6, the forward end portion of each of the actuators, members or slidable rods 70 and 76 supports a hollow key stem 83, each key stem being bored out as indicated at 84 to fit over and slidably engage 'or loosely connect with its associate rod, member or stop controlling device. The key stems or devices 83 slidably engage in bearing openings in the parallel walls 2 and 2 of the left-hand front corner post 2 and also pass through holes in a plate 85 which is clamped between the front of said corner post and the usual front plate 86 by the screws 87, the front plate being cut away as indicated at 88 where the key stems pass through the plate 85. Forward of the front plate the stems 83 are provided with finger keys or buttons, the up r key 89 being marked with suitable in icating devices as the word Set, and the lower key 90 having also suitable indicating marks as Clear. Behind the post wall 2, each of the rods or members 70 and 76 is surrounded by and supports a' cylindrical barrel or housing 91, each barrel being open at its front end which normally abuts against the rear face of the corner post and terminating at the rear in a hub portion 92 which receives a set screw that secures the barrel to its supporting rod. Within the bore 91 of each barrel is arranged a coiled compressible spring or power device 95, said spring surrounding and being mounted on the associate supporting rod and being confined between the bottom face of the bore 91 and a collar 96 which is adjustably secured on the inner end of the associate key stem 83 which is threaded for the purpose as indicated at 97, said collar being formed with a corresponding tapped opening. The collar, which constitutes means for compressing or storing power in the associate power spring, is maintained set in proper position on its key stem by a check nut 98 which is threaded on the portion 97 forward of the collar and is screwed up tight against said collar after it has been properly adjusted. A screw stop or arresting device 99 is threaded into each barrel 91 and projects partway into the bore thereof in position to cooperate with the check nut 01' arresting device 98 to limit the forward movement of the key stem 83 which upports said check nut.

It will be understood that the rods 70 and 76 are moved forward by the associate restoring springs 80 and 81 until arrested by the contact of the barrels or arresting devices 91 with the corner post 2, thus determining the limit of movement and the normal position of the rods and the barrels supported thereon as well as of the screw stops 99. Also it will be understood that the nuts 98 contacting withsaid screw stops limit the forward movements of the key stems when they are being pushed forward on and relatively to their supporting rods and thereby determine the normal positions of said key stems. Preferably the power springs are practically inert at the moment of arrest. Each collar 96 is provided with a lug or extension 96 which projects outward through a slot 100 out or otherwise formed longitudinally in the barrel 91, said slot being of sufiicient width to permit slid ing movements of the lug 96 longitudinally thereof. From Fig. 4 it will be plain that the lug 96 of the upper collar projects downward through the associate slot 100i which slot is formed in the under side of the barrel 91; while the lug 96 of the lower collar projects upward through the associate slot 100 and the lower barrel 91, the last named slot being formed in the upper side of said barrel. The lugs 96 constitute means for releasing detent members which hold the barrels 91 against substantial rearward movement and prevent actuation of the slidable rods. In the piesent instance said detent members are in the form of oppositely arranged arms 101 which extend forward one above the other between the barrels 91, each of said arms being pivoted near its rear. end on a screw 102 which is secured to the side of the bracket 78 between the ears 7 7 Each of said detent arms 101 is provided with a locking shoulder 103 which cooperates with the annular shoulder 104 formed between the body portion of the associate barrel 91 and its hub portion 92, said hub portion, as is shown, being of lesser diameter." Forward of the shoulder 101 each arm 101 terminates in a pointed head or end portion 105, said end portion projecting into the associate slot 100 and having an inclined or cam edge 10.3 which extends downward out of the slot and into the path of the associate lug 96 which, as shown, is rounded for coiiperation with said inclined edge, the inclined edge terminating at the forward end of the portion 105 at a slightly greater distance from the face of the periphery of the barrel than does the lug 96. Near their ends the arms 101 are provided with oppositely projecting lugs 106 around which is coiled a spring 107. The spring acts on both arms 101, tending to swing them apart and force their end portions 105 within the associate slots 100, this movement being limited in any suitable way by the engagement of the end. portions 105 with the springs 95. At this time or normally the ends of the lugs 106 are separated as shown in Fig. 4.

In operation when the stop set key 89 is pressed in its motion will be transmitted through the collar 96 and spring 95 to the barrel 91 which will be moved slightly rcarward until arrested by the engagement of the shoulder 104 with the shoulder 103, these shoulders being normally slightly separated. After this slight initial movement the barrel 91 will remain motionless as the key 89 is pushed in and consequently the spring 95 will be compressed by the collar 96 which will continue to move rearward within the barrel, the key stem 83 at the same time sliding rearward on the rod until the lug 96 engages with the cam edge 10?), forcing the head 105 downward and swinging the arm 101 on its pivot, this swinging movement continuing until the shoulder 101 disengagcs from the shoulder 1033. thereby releasing the barrel'91 and the rod 70. As soon as the barrel is released the compressed spring 95 forces it and the rod 70 rearward and the power stored in the spring is suflicient to overcome the spring crank arm 69, rock shaft 63, crank arm 2 and link 70, forcing the ejector 57' downward and electing the underlying stopwithin the magazine, said stop being pushed downward by the ejector through the mouth and to actuate the train of stop control; ling or ejecting devices comprising the of the magazine and on to the column stop bar. It will be apparent that as soon as the detent device or shoulder 104 frees the barrel 91 the ejector mechanism will be taken out of the control of the finger key 89 and the entire ejecting operation proper will be performed by the spring 95, the function of the key 89 being first to compress said spring and then to release it so that it may perform its work. When the key 89 is released the parts will be restored to normal position by the springs 80 and 95. Similarly, a retracting operation is effected by actuating the clearing key 90 which is pressed in first, compressing the associate 5 ring 95 and then through the lug 96 re easing or tripping the arm 101 to permit the compressed spring, acting through the barrel 91 and rod 76, to actuate the retracting devices and cause the retractor 58 to raise the column stop that is in register therewith oil the stop bar and a force it through the magazine mouth into the magazine. In Fig. 5 the parts of the retriicting mechanism are shown near the end of the operation of the key 90 and just as. the release of the compressed spring 95 is about to take place.

The lugs 106 are adapted to cooperate with each other to act as safety devices to prevent the simultaneous effective operation of the keys 89 and 90 as will best be understood from Fig. 6. Said lugs are of ilch length that their ends will engage it 56th he s be premed in to ether and as a reunite luch engagement t e arms 101 will be arrested before the shoulders 103 have moved far enough to release their hssociate barrels 91.

A: a further measure of precaution improved and simplified means are provided or automatically spacing the carriage azfter a stopejecting operation, thus preventing one mop from being e'ected on to another with the possibilit o jamming the ejecting mechanism an the carria e. Said imroved means comprise as ilustrated in i 1 and 2 an an lar member or arm 10 which is secure by a .screw 109 or otherwise to the link 19 of the es'capement mechanism. The arm 108 extends rearwardly and is ofi-set toward the left, terminoting in an upwardly extending portion 110 which is provided with a laterally extending horizontal lip or ledge 111 that underlies the crank arm 62, bein normally se arated therefrom as shown in Fig. 1".

ien the ejecting devices are operated the arm 62 will swing downward toward the end of its movement far enough to contact with the lip 111 and force it downward, thus forcin downward the link 19 with which said ip and the arm 108 are rigidly connected, therebyoperating the escapement devices and causing a letter space movement of the carriage toward the left after the stop has been ejected; the ejected stop being thus carried out of r'egister with the magazine slot-way.

Various changes may be made without departing from the spirit and scope of my invention.

What I claim as new and desire to secure by Letters Patent, is I 1.
